A low pass filter manufactured by RLC Electronics, model number L-1509A, is available. The 3-dB cutoff frequency is about 3.05 GHz.
We measured the following cutoff frequencies: 3-dB cutoff frequency: 3.05 GHz 6-dB cutoff frequency: 3.06 GHz 10-dB cutoff frequency: 3.07 GHz 20-dB cutoff frequency: 3.09 GHz Measurements were made with cared-for, but ultimately uncalibrated, hobby-grade equipment so interpret the data presented here accordingly.
The unit has an F-SMA connector on each end. A data sheet was not available for this device.
This is a 50 Ohm device, tested in a 50 Ohm environment. It is used and in working condition, with signs of normal use and wear. The RLC Electronics L-1509A unit, shown in the photos, is the only item included in this listing. The photos were taken on a 1 cm grid. I will combine multiple items together to reduce shipping costs and will mail one or two business days after receiving cleared payment.
